Yes, but one should not underestimate the impact of "regression to the mean" (cited above).
Two genius-level parents will have children whose intelligence is shifted slightly to the right on the bell curve. The chances of any single child also being a genius is maybe only twice that of a child selected at random from the general population (i.e.: the chance shifts from "very low" to only "low").
It is vital that high-I.Q. parents bear this fact in mind.

Case in point: Albert Einstein had a two sons. One became an engineer, doing well but not rocking the world.

This is a problem with “elites”. Their parents may have been brilliant. The offspring, not necessarily.
They fear brilliant competitors emerging from the middle class, which is why they seek to sabotage the education system.
There is also a theory under research in high-IQ areas like Silicon Valley that many autistic children are the result of two high-IQ parents, particularly if the father or grandfather was in engineering. An article about it appeared in Wired magazine maybe 20 years ago. While some autistic kids may be language-impaired or otherwise quite visibly handicapped, others are “savants”, whose very high IQ must contend with social awkwardness and behavioral tics in the personallity.
